Hi everyone.
I had been suffering from low libido & extreme premature ejaculation, for many years (I am 34 yrs old). I could ejaculate only once/day, & it made me very sore in that region for the rest of the day, my testicles felt empty & loose, & any further erection would feel very painful.
I used to get good erections in the monring, & very low in the evening/night.

Since the past year, I have been seeing endocrinologists & undergoing blood tests & treatments.

I would like your opinions/feedback, based on your experiences in dealing with similar issues, which should help me, as well as, hopefully, others.

I started taking Vit D3 2000IU, once a day.
My earlier doctor was saying T is still "within range" & so he didnt want to do anything. After reading in these forums, I insisted on testing the other components.

Alarmed by the high prolactin, he wanted another blood test, where it came lower.
August 2010 (morning)
prolactin : 21 (2-18 ng/ml) // ----> hi, but much lower than 42

Is it normal for prolactin to vary so much over the course of a few days?

After this, I was prescribed Arimidex. I started with 0.5mg/day for 2 weeks, & then continued on 0.25mg/every other day.

After 3 weeks with no change, I felt a hugh increase in libido, & I could ejaculate 3-4 times/everyday (for the first time in years!). However, this lasted only for ~5 days, & then gradually decreased. Assuming my E2 had gone too low, I reduced my dosage further to 0.25mg/every 3-4 days. But my condition didnt improve.
But I did feel my testicles had grown slightly bigger & always felt full.

Since my E2 was still high, I increased Arimidex to 1mg/day. It has been 1 month, but I have not seen any improvement in my libido. I do get nocturnal erections, & can ejaculate once/day, but not more (primarily morning).

My evening erections are not good. Is it due to all the T produced in the night/morning being used up/converted by evening?

I have heard that Arimidex is powerful & fast-acting & should see improvement in a few days. I have been on it for ~3 months, but not seen much.

Is the high prolactin causing my libido issues (inspite of normal T)? Should I request a prescription for Cabergoline/Bromocriptine?

Since I have been facing diverse issues - extreme premature ejaculation, low libido, low T, high E2, & high prolactin - I am thinking they are all related, there is one root cause which is affecting everything.
& that I should look for a treatment for the root cause, instead of attacking specific issues like high E2, high prolactin, etc.

///////////////////////////////////
Some of my history (dont know if it could be related to libido issue) :
I have always been physically very active, running, hiking, weight training. Though I have good tone on my muscles, I could never really add hugh musculature/bulk/size (guess it is due to low T?). My height is 5 feet 3 inch, & I used to weigh ~130 lbs.

I had hugh extreme acne since age 13-25 yrs; & had taken a variety of medicines. Even now, I still keep getting acne breakups. Dont know if acne medicines could effect hormones, as it was from around the time of puberty.

I have high cholesterol.
The past 5 years, I have been under a lot of stress, & added quite a lot of fat around the belly, shoulders, chest, etc (I hope it is not man-boobs from high E2/prolactin). My weight increased to ~155 lbs.
Since the past ~8months, I have been drastically changing my diet, & have reduced my weight to ~130 lbs, lowered cholesterol, etc.

Have you done an MRI to check for a benign tumor in your pituitary? That could explain the high prolactin (which would cause all the rest). Have you checked your cortisol? I heard high cortisol for extended periods (caused by stress most times) can cause a hormone imbalance of this sort. Also, have you checked your blood iron and most importantly your ferritin saturation index? Problems in iron metabolism can cause iron deposition in the glands leading to low T and all that.

ANother question. When you ejaculate do you have an normal orgasm? Is it pleasureful?

sorry to hear of your issues. I just found out about my low T as well I am 35, however i had tested low last year and the dr said lets wait and see, however during this time my sex drive diminished to zilch. so they retested me last month and as suspected it was still extremely low. I started on the shot today, i wanted to do the androgel. but my dr was not in the office today so i went ahead with the shot to see if something will improve while i wait to hear back from my dr, my insurance will cover the androgel however it has to have prior authorization which i am sure they will do with no issue. I just now have to wait and see. I know i can't expect any improvement for weeks from the shot, but at least i did something in the mean time....I never knew so many guys in my age group had this issue!!! Glad I found this board.
